What does it mean for a sculpture to be described as 'organic' or a diagram of 'morphological forces'? These were questions that preoccupied Modernist sculptors and critics in Britain as they wrestled with the artistic implications of biological discovery during the 1930s. In this lucid and thought-provoking book, Edward Juler provides the first detailed critical history of British Modernist sculpture's interaction with modern biology. Discussing the significant influence of biologists and scientific philosophers such as D'Arcy Wentworth Thompson, Julian Huxley, J. S. Haldane and Alfred North Whitehead on interwar Modernist practice, this book provides radical new interpretations of the work of key British Modernist artists and critics, including Henry Moore, Barbara Hepworth, Paul Nash and Herbert Read. Innovative and interdisciplinary, this pioneering book will appeal to students of art history and the history of science as well as anyone interested in the complex, interweaving histories of art and science in the twentieth century.
